Exercise dependence and orthorexia nervosa in Crossfit: exploring the role of perfectionism

Striving for the perfect diet? The mediating role of perfectionism in the relationship between obsessive compulsive symptoms and traits of Orthorexia Nervosa

BACKGROUND

Orthorexia Nervosa (ON) is a disordered eating style involving an unhealthy obsession with 'healthy' or 'clean' eating. Its aetiology is still poorly understood and is not yet recognised in diagnostic manuals. While ON has been associated with Obsessive Compulsive (OC) symptoms and perfectionism, no study to date has looked at the relationship between OC symptoms and ON tendencies via perfectionism, or the influence of two facets of perfectionism in this relationship, namely evaluative concern and achievement striving. Examining the potential role of perfectionism helps to understand the aetiology of ON as well as inform potential treatments tailored specifically for ON and comorbid OC symptoms.

METHODS

In this cross sectional study, we tested 507 participants (n = 70 males, n = 69 at risk of ON) on questionnaires measuring OC symptoms, perfectionism and ON symptoms. We ran two mediation analyses to look at the overall relationship between perfectionism and OC and ON symptoms (Model 1) as well as the specific contribution of evaluative concern and achievement striving in the relationship between OC and ON symptoms (Model 2).

RESULTS

We found that perfectionism partially mediated the relationship between OC and ON symptoms. Specifically, we found that while achievement striving and evaluative concern were associated with OC symptoms, only achievement striving was significantly associated with ON symptoms, mediating the relationship between OC and ON symptoms.

CONCLUSIONS

This study highlighted the role of one key facet of perfectionism (achievement striving) in the aetiology of ON. The role of achievement striving was indicated as a transdiagnostic construct explaining the link between ON and OC symptoms. These findings are discussed in terms of their implications for treatment models, specifically in terms of the potential role of targeting perfectionism in ON treatment.

The Associations between Obsessive Compulsive Personality Traits, Self-Efficacy, and Exercise Addiction

Exercise addiction refers to maladaptive exercise patterns involving compulsivity and addiction-like behaviors. Exercise addiction has been found to relate to negative physical and mental health outcomes such as heart abnormalities, physical injuries, and interpersonal conflicts. Based on the social cognitive theory, this study investigated the extent to which the interplay of obsessive compulsive personality disorder (OCPD) traits and self-efficacy beliefs would influence the development and maintenance of exercise addiction. A total of 1228 college students in the United States responded to an online survey. Based on cut-off scores of the Revised Exercise Addiction Inventory, the prevalence estimates of exercise addiction were 4.0% for males and 1.8% for females. Results showed that males are more prone to exercise addiction than females. Also, OCPD traits and self-efficacy significantly predicted exercise addiction after controlling for age and sex. Self-efficacy acted as a moderator in influencing the relationship between OCPD traits and exercise addiction, especially for females. At high levels of self-efficacy, more OCPD traits were significantly associated with a higher risk of exercise addiction. However, at low levels of self-efficacy, there was no association between OCPD traits and exercise addiction. The findings suggest that public education and intervention for exercise addiction should attend to the interplay between personality factors and sex.

The relationship between personality traits and willingness to undergo cosmetic surgery in the non-clinical population - a systematic review and meta-analysis

Objective

Conducting a systematic review and meta-analysis to synthesize previously obtained results regarding the relationship between interest in cosmetic surgery and personality traits.

Methodology

A series of criteria were applied (at the level of design, independent variables, dependent variable, participants) in order to decide which existing studies could be considered eligible for inclusion in the meta-analytic procedure. The identification of research that met the eligibility criteria was carried out with the help of the electronic search function in the following databases: ScienceDirect, PsycInfo, Web of Science, Scopus, Springer, and PubMed. Following this approach left 13 studies that were then subjected to the final analysis and included in the meta-analysis.

Results

The researchers' expectations were partially supported by the results of the analyses, thus demonstrating the existence of a significant relationship between perfectionism (socially prescribed perfectionism; perfectionistic self-promotion), appearance-based rejection sensitivity, and interest in pursuing esthetic surgery.

Discussions

Identifying these relationships will allow cosmetic surgeons to understand both the mechanisms underlying this decision and the need for psychological assessment/counseling before patients undergo such procedures. It will also allow psychologists to develop best practice guidelines for how they relate to the patient before they perform cosmetic surgery. At the same time, psychotherapists will be able to devise targeted and personalized interventions for each personality profile, so that the decision to undergo an esthetic operation is not made based on a dispositional trait (fear of rejection, stress caused by body dissatisfaction).

Maternal Bonding as a Protective Factor for Orthorexia Nervosa Risk in Dietetics Students

This study aimed to determine the prevalence of the risk of orthorexia nervosa (ON) in dietetics students in Greece, and its relationship with diet, risk of eating disorder (ED), body mass index (BMI), body image flexibility, and parental attachment. The participants were 132 dietetics students, with a mean age of 22.94 ± 3.5 years, who completed a series of questionnaires that recorded sociodemographic, clinical, and anthropometric characteristics; adherence to the Mediterranean diet (MedDiet); ON indicators as determined by the ORTO-15 questionnaire; body image flexibility, with the Body Image-Acceptance and Action Questionnaire (BI-AAQ-5); the risk for ED as assessed using the EAT-26; anxiety level according to the STAIT 6 instrument; and recollection of their parents' attitudes towards them during the first 16 years of life, with the Parental Bonding Instrument (PBI). ON risk appeared to be significantly associated with BMI (p = 0.002), exercise frequency (p = 0.023), anxiety level (p = 0.002), risk of ED (p < 0.001), body image inflexibility (p < 0.001), and inversely with the affectionate constraint of maternal bonding (p = 0.036). In conclusion, disordered eating behaviors and body shape concerns are prevalent among dietetics students, with parental attachment to the mother influencing their occurrence. Identification of potential ON and development of prevention mechanisms during childhood could help eliminate these concerns and improve the lives of dietetics students.

The indirect role of orthorexia nervosa and eating attitudes in the association between perfectionism and muscle dysmorphic disorder in Lebanese male University students - results of a pilot study

BACKGROUND

The literature highly concentrates on disorders related to body image among women but only minimally when it comes to the male population; hence, in order to provide general practitioners, and primary care physicians in general, and psychiatrists in particular, with additional information concerning muscle dysmorphia among male university students in Lebanon, this study seemed essential, and was therefore conducted to (1) identify the prevalence of MDD, and (2) evaluate the indirect effect of eating attitudes in general and orthorexia nervosa in particular, in the association between perfectionism and muscle dysmorphic disorder (MDD) among a sample of male university students.

METHODS

In this cross-sectional study conducted between September 2021 and May 2022, 396 male university students from multiple universities in Lebanon filled the online Arabic questionnaire.

RESULTS

The results showed that 26 (6.6%) of the participants had MDD. Orthorexia nervosa and eating attitudes mediated the association between perfectionism and MDD; higher perfectionism was significantly associated with higher ON and more inappropriate eating; higher ON and more inappropriate eating were significantly associated with higher MDD, whereas perfectionism had a significant total direct effect on MDD. The high prevalence of MDD among male university students in Lebanon implies further investigation on the national level in the country.

CONCLUSION

Awareness campaigns among the university students could be adopted at the national level to increase the level of knowledge on the concepts of obsessive self-destructive perfectionism, orthorexia nervosa and muscle dysmorphia.

Perfectionism and Exercise Dependence: the Role of Basic Psychological Needs and Introjected Regulation

Using a self-determination theory (SDT) framework, the aims of our study were to examine the perfectionism-exercise dependence relationships, and whether basic psychological needs and introjected regulation explained these relationships. Distance runners (n = 260, M age: = 42.41 years; SD: = 11.95 years, n = 144 female) completed measures of multidimensional perfectionism (self-oriented perfectionism (SOP); socially prescribed perfectionism (SPP)), basic psychological need satisfaction and thwarting, introjected regulation, and exercise dependence. Bivariate correlations revealed significant positive SOP-exercise dependence and SPP-exercise dependence relationships. Structural equation modelling suggested that, in combination, perfectionism, basic psychological need satisfaction/thwarting and introjected regulation accounted for large amounts of variance in exercise dependence. Tests of indirect effects showed that the SPP-exercise dependence relationship was mediated by basic psychological need thwarting and introjected regulation. Our findings suggest that while the SOP-exercise dependence relationship is more direct, need thwarting and introjected regulation represent a motivational signature of SPP and exercise dependence.
